DESCRIPTION

Numerous details are described in order to provide a thoroughunderstanding of the example implementations shown in the drawings.However, the drawings merely show some example aspects of the presentdisclosure and are therefore not to be considered limiting. Those ofordinary skill in the art will appreciate that other effective aspectsand/or variants do not include all of the specific details describedherein. Moreover, well-known systems, methods, components, devices, andcircuits have not been described in exhaustive detail so as not toobscure more pertinent aspects of the example implementations describedherein.

Lenticular displays are capable displaying different content atdifferent angles. For example, when viewing a lenticular display from afirst angle, a video clip is seen and when viewing the lenticulardisplay from a second angle, a different video clip is seen.

In various implementations, a lenticular display includes a matrix ofpixels over which a lenticular lens pattern is laid. In variousimplementations, a first set of the matrix of pixels is visible from afirst angle, a second set of the matrix of pixels is visible from asecond angle, a third set of pixels is visible from a third angle, andso on.

In various implementations described below, this feature of lenticulardisplays is used to present different content to different users as theymove with respect to the lenticular display. For example, in variousimplementations, a first user and a second user are tracked by an imagesensor and first content and second content are displayed to the firstuser and the second user at whatever angle they are with respect to thelenticular display.

FIG. 1 illustrates a first perspective view of an example operatingenvironment at a first time 100A. The example operating environment atthe first time 100A includes an electronic device 101 having an imagesensor 112 and a lenticular display 110. The example operatingenvironment at the first time 100A includes a first user 120A and asecond user 120B of different heights viewing the lenticular display. Atthe first time, the first user 120A is at a first location and thesecond user 120B is at a second location.

Although FIG. 1 illustrates only two users in the example operatingenvironment, in various implementations, any number of users may bepresent in the example operating environment and have different contentpresented thereto.

FIG. 2 illustrates a second perspective view of the example operatingenvironment at the first time 100A. The second perspective view isillustrated from a position behind the first user 120A looking towardsthe device 101. From this angle, first content 130A can be seen on thelenticular display 110. The first content 130A includes a cylinder 140viewed from particular vertical angle. At the particular vertical angle,the top 141 of the cylinder 140 can be seen.

FIG. 3 illustrates a third perspective view of the example operatingenvironment at the first time 110A. The third perspective view isillustrated from a position behind the second user 120B looking towardsthe device 101. From this angle, second content 130B can be seen on thelenticular display 110. The second content 130B includes the samecylinder 140 viewed from a different vertical angle. At the differentvertical angle, the top 141 of the cylinder 140 cannot be seen. However,at the different vertical angle, the bottom 142 of the cylinder 140 canbe seen.

In various implementations, the first content 130A and the secondcontent 130B are two different images. In various implementations, thefirst content 130A and the second content 130B are two different videos.In various implementations, the first content 130A and the secondcontent 130B are different versions of the same underlying content. Forexample, the second content 130B may be a censored version of the firstcontent 130A.

In various implementations, the first content 130A and/or second content130B is based on metadata regarding the user viewing the content. Forexample, if the first user 120A is associated with metadata indicatingthat the first user 120A has permission to view certain content, butthat second user 120B is not associated with metadata indicating thatthe second user 120B has permission to view the certain content, thefirst content 130A may include that certain content whereas the secondcontent 130A may not include that certain content, but rather, othercontent. For example, the first user 120A may be associated withmetadata indicating that the first user 120A has permission to watchtelevision shows rated TV-MA or less, whereas the second user 120B isassociated with metadata indicating that the second user 120B haspermission to watch television shows rated TV-PG or less. Thus, thefirst content 130A may include a TV-MA rated television show and thesecond content may include a different show (rated TV-PG or less) or acensored version of the TV-MA rated television show.

In various implementations, as in FIGS. 2 and 3, the first content 130Aand the second content 130A are different perspective views of the sameobject or scene. In various implementations, the object is a virtualobject. In various implementations, the object is a three-dimensionalobject. In various implementations, the scene is a virtual scene. Invarious implementations, the scene is a three-dimensional scene.

FIG. 4 illustrates a top view of the example operating environment atthe first time 100A. The device 101 determines a first horizontal angle(θ₁) of the first user 120A with respect to a line 115 perpendicular tothe lenticular display 110 and a second horizontal angle (θ₂) of thesecond user 120B with respect to the line 115 perpendicular to thelenticular display 110. In FIG. 4, the first horizontal angle (θ₁) isapproximately −30 degrees and the second horizontal angle (θ₂) isapproximately 45 degrees.

In various implementations, the device 101 determines the firsthorizontal angle (θ₁) and the second horizontal angle (θ₂) using theimage sensor 112 to capture an image of the first user 120A and thesecond user 120B and detecting the first user 120A and the second user120B in the captured image. The device 101 controls the lenticulardisplay 110 to display the first content 130A at the first horizontalangle (θ₁) (e.g., to the first user 120A) and the second content 130B atthe second horizontal angle (θ₂) (e.g., to the second user 120B).

FIG. 5 illustrates a top view of the example operating environment at asecond time 100B. At the second time, the first user 120A has moved fromthe first position to a third position and the second user 120B hasmoved from the second position to a fourth position. The device 101determines a third horizontal angle (θ₃) of the first user 120A withrespect to the line 115 perpendicular to the lenticular display 110 anda fourth horizontal angle (θ₄) of the second user 120B with respect tothe line 115 perpendicular to the lenticular display 110. In FIG. 5, thethird horizontal angle (θ₃) is approximately −60 degrees and the fourthhorizontal angle (θ₄) is approximately −30 degrees.

The device 101 controls the lenticular display 110 to display the firstcontent 130A at the third horizontal angle (θ₃) (e.g., to the first user120A) and the second content 130B at the fourth horizontal angle (θ₄)(e.g., to the second user 120B). Thus, even though the first horizontalangle (θ₁) and the fourth horizontal angle (θ₄) are, coincidentally, thesame, different content is displayed at that angle at the first time(e.g., the first content 130A to the first user 120A) and the secondtime (e.g., the second content 130B to the second user 120B).

FIG. 6 illustrates a top view of the example operating environment at athird time 100C. At the third time, the first user 120A remains at thethird position and the second user 120B remains at the fourth position.However, the device 101 has moved (e.g., rotated), changing thehorizontal angles of the users with respect to the line 115perpendicular to the lenticular display 110.

The device 101 determines a fifth horizontal angle (θ₅) of the firstuser 120A with respect to the line 115 perpendicular to the lenticulardisplay 110 and a sixth horizontal angle (θ₆) of the second user 120Bwith respect to the line 115 perpendicular to the lenticular display110. In various implementations, the device 101 determines the fifthhorizontal angle (θ₅) and the sixth horizontal angle (θ₆) based on datafrom a pose estimation unit of the device 101, such as an inertialmeasurement unit (IMU), IR encoder, or potentiometer. In FIG. 6, thethird horizontal angle (θ₃) is approximately −45 degrees and the fourthhorizontal angle (θ₄) is approximately −15 degrees. The device 101controls the lenticular display 110 to display the first content 130A atthe fifth horizontal angle (θ₅) (e.g., to the first user 120A) and thesecond content 130B at the sixth horizontal angle (θ₆) (e.g., to thesecond user 120B).

FIG. 7 illustrates a top view of the example operating environment atthe third time 100C in which each eye of each user is presenteddifferent content. At the third time, the first user 120A remains at thethird position, the second user 120B remains at the fourth position, andthe device 101 has been moved.

The device 101 determines the fifth horizontal angle (θ₅) of a first eyeof the first user 120A with respect to the line 115 perpendicular to thelenticular display 110, the sixth horizontal angle (θ₆) of a first eyeof the second user 120B with respect to the line 115 perpendicular tothe lenticular display 110, a seventh angle (θ₇) of a second eye of thefirst user 120A with respect to the line 115 perpendicular to thelenticular display 110, and an eighth angle (θ₈) of a second eye of thesecond user 120B with respect to the line 115 perpendicular to thelenticular display 110.

The device 101 controls the lenticular display 110 to display the firstcontent 130A at the fifth horizontal angle (θ₅) (e.g., to the first eyeof the first user 120A) and the second content 130B at the sixthhorizontal angle (θ₆) (e.g., to the first eye of the second user 120B).The device 101 further controls the lenticular display 110 to displaythird content at the seventh horizontal angle (θ₇) (e.g., to the secondeye of the first user 120A) and fourth content at the eighth horizontalangle (θ₈) (e.g., to the second eye of the second user 120B).

In various implementations, the first content 130A and the third contentare different perspectives of the same object or scene. Similarly, invarious implementations, the second content 130B and the fourth contentare different perspectives of the same object or scene.

FIG. 8 illustrates a side view of the example operating environment atthe third time 100C. The device 101 determines a first vertical angle(φ₁) of the first user 120A with respect to the line 115 perpendicularto the lenticular display 110 and a second vertical angle (φ₂) of thesecond user 120B with respect to the line 115 perpendicular tolenticular display 110. The device 101 controls the lenticular display110 to display the first content 130A at the fifth horizontal angle (θ₅)(e.g., to the first user 120A) based on the first vertical angle (φ₁)and the second content 130B at the sixth horizontal angle (θ₆) (e.g., tothe second user 120B) based on the second vertical angle (φ₂).

As a particular example, in various implementations, the first content130A includes a virtual three-dimensional object (e.g., a cylinder)displayed from a first horizontal perspective based on the fifthhorizontal angle (θ₅) and a first vertical perspective based on thefirst vertical angle (φ₁), the third content includes the same virtualobject displayed from a second horizontal perspective based on theseventh horizontal angle (θ₇) and the first vertical perspective basedon the first vertical angle (φ₁), the second content 130B includes thesame virtual object displayed from a third horizontal perspective basedon the sixth horizontal angle (θ₆) and a second vertical perspectivebased on the second vertical angle (φ₂), and the fourth content includesthe same virtual object displayed from a fourth horizontal perspectivebased on the eighth horizontal angle (θ₈) and the second verticalperspective based on the second vertical angle (φ₂). Thus, each userstereoscopically views a virtual three-dimensional object with thecorrect vertical perspective for that user.

FIG. 9 is a flowchart representation of a method 900 of operating alenticular display in accordance with some implementations. In variousimplementations, the method 900 is performed by a device with one ormore processors, non-transitory memory, an image sensor, and alenticular display (e.g., the device 101 of FIG. 1). In someimplementations, the method 900 is performed by processing logic,including hardware, firmware, software, or a combination thereof. Insome implementations, the method 900 is performed by a processorexecuting instructions (e.g., code) stored in a non-transitorycomputer-readable medium (e.g., a memory).

The method 900 begins, in block 910, with the device capturing, usingthe image sensor, a first image.

The method 900 continues, in block 920, with the device determining,from the first image, a first horizontal angle of a first user at afirst time with respect to a line perpendicular to the lenticulardisplay and a first horizontal angle of a second user at the first timewith respect to the line perpendicular to the lenticular display. Invarious implementations, the first time is when the first image iscaptured. For example, in FIG. 4, the device (based on an image capturedusing the image sensor 112) determines the first horizontal angle (θ₁)and the second horizontal angle (θ₂). In various implementations, thedevice 101 employs a face detection algorithm on the first image todetermine locations in the image of the first user and the second user.The locations in the image are mapped to horizontal (and, in variousimplementations, vertical) angles with respect to the line perpendicularto the lenticular display.

The method 900 continues, in block 930, with the device displaying, viathe lenticular display, first content at the first horizontal angle ofthe first user and second content, different than the first content, atthe first horizontal angle of the second user.

In various implementations, the first content includes a first image andthe second content includes a second image different than the firstimage. In various implementations, the first content includes a firstvideo and the second content includes a second video different than thefirst video.

In various implementations, the first content includes a first versionof content and the second content includes a second version of thecontent different from the first version of the content. For example, invarious implementations, the second version of the content is a censoredversion of the first version of the content.

In various implementations, displaying the first content at the firsthorizontal angle of the first user includes displaying an object orscene at a first perspective and displaying the second content at thefirst horizontal angle of the second user includes displaying the objector scene at a second perspective different than the first perspective.For example, in FIGS. 2 and 3, the device 101 displays, for the firstuser 120A, a cylinder 140 from a first vertical perspective at which thetop 141 is visible and displays, for the second user 120B, the cylinder140 from a second vertical perspective at which the top 141 is notvisible, but at which the bottom 142 is visible.

In various implementations, the method 900 further includes determining,based on the first image, an identity of the first user and an identityof the second user, wherein the first content is based on the identityof the first user and the second content is based on the identity of thesecond user. For example, in various implementations, the first user isassociated with a first subscription video service account and thesecond user is associated with a second subscription video serviceaccount and a respective “next episode” is displayed to each user. Invarious implementations, the method 900 further includes determining,from the first image, a first vertical angle of the first user at thefirst time with respect to the line perpendicular to the lenticulardisplay and a first vertical angle of the second user at the first timewith respect to the line perpendicular to the lenticular display. Forexample, in FIG. 8, the device 101 determines the first vertical angle(φ₁) of the first user and the second vertical angle (φ₂) of the seconduser. In various implementations, wherein displaying the first contentat the first horizontal angle of the first user and the second contentat the first horizontal angle of the second user is based on the firstvertical angle of the first user and the first vertical angle of thesecond user. For example, in FIGS. 2 and 3, the device 101 displays, forthe first user 120A, a cylinder 140 from a first vertical perspective atwhich the top 141 is visible and displays, for the second user 120B, thecylinder 140 from a second vertical perspective at which the top 141 isnot visible, but at which the bottom 142 is visible. Accordingly, invarious implementations, displaying the first content at the firsthorizontal angle of the first user includes displaying an object orscene at a first vertical perspective based on the first vertical angleand displaying the second content at the first horizontal angle of thesecond user includes displaying the object or scene at a second verticalperspective based on the second vertical angle.

In various implementations, the first content and the second content aredisplayed at the same vertical perspective based on the first verticalangle and the second vertical angle. For example, in variousimplementations, a virtual object is displayed at a vertical perspectivebased on the average of the first vertical angle and the second verticalangle.

The method 900 continues, at block 940, with the device determining asecond horizontal angle of the first user at a second time, differentthan the first time, with respect to the line perpendicular to thelenticular display and a second horizontal angle of the second user atthe second time with respect to the line perpendicular to the lenticulardisplay. For example, whereas in FIG. 4, the device 101 determines thefirst horizontal angle (θ₁) of the first user 120A at the first time andthe second horizontal angle (θ₂) of the second user 120B at the firsttime, in FIG. 5, the device 101 determines the third horizontal angle(θ₃) of the first user 120A at the second time and the fourth horizontalangle (θ₄) of the second user 120B at the second time.

In various implementations, the second horizontal angle of the firstuser is different than the first horizontal angle of the first user. Forexample, in FIGS. 4 and 5, the third horizontal angle (θ₃) is differentthan the first horizontal angle (θ₁). In various implementations, thesecond horizontal angle of the second user is the same as the firsthorizontal angle of the first user. For example, in FIGS. 4 and 5, thefourth horizontal angle (θ₄) is the same as the first horizontal angle(θ₁).

In various implementations, the method 900 includes capturing, using theimage sensor, a second image, wherein determining the second horizontalangle of the first user and the second horizontal angle of the seconduser is based on the second image. In various implementations, themethod 900 includes receiving data from a pose estimation unit (IMU),wherein determining the second horizontal angle of the first user andthe second horizontal angle of the second user is based on the data fromthe pose estimation unit.

The method 900 continues, in block 950, with the device displaying, viathe lenticular display, the first content at the second horizontal angleof the first user and the second content at the second horizontal angleof the second user.

In various implementations, the method 900 further includes determininga third horizontal angle of the first user at the first time withrespect to the line perpendicular to the lenticular display and a thirdhorizontal angle of the second user at the first time with respect tothe line perpendicular to the lenticular display. For example, in FIG.7, the device 101 determines the seventh horizontal angle (θ₇) of thefirst user 120A and the eighth horizontal angle (θ₈) of the second user120B. The method 900 further includes displaying, via the lenticulardisplay, third content at the third horizontal angle of the first userand fourth content, different than the third content, at the thirdhorizontal angle of the second user.

In various implementations, displaying the first content at the firsthorizontal angle of the first user includes displaying an object orscene at a first horizontal perspective based on the first horizontalangle of the first user and displaying the third content at the thirdhorizontal angle at the third horizontal angle of the first userincludes displaying the object or scene at second horizontal perspectivebased on the third horizontal angle of the first user.

Insome implementations, the memory 1020 includes non-volatile memory, suchas one or more magnetic disk storage devices, optical disk storagedevices, flash memory devices, or other non-volatile solid-state storagedevices. The memory 1020 optionally includes one or more storage devicesremotely located from the one or more processing units 1002. The memory1020 comprises a non-transitory computer readable storage medium.

The operating system 1030 includes procedures for handling various basicsystem services and for performing hardware dependent tasks. In someimplementations, the content presentation module 1040 is configured topresent different content to different users at different angles via thelenticular display 1012.

In some implementations, the content presenting unit 1044 is configuredto display, via the lenticular display, first content at the firsthorizontal angle of the first user and second content, different thanthe first content, at the first horizontal angle of the second user. Tothat end, in various implementations, the content presenting unit 1044includes instructions and/or logic therefor, and heuristics and metadatatherefor.

Although the user detection unit 1042 and the content presenting unit1044 are shown as residing on a single device (e.g., the device 101 ofFIG. 1), it should be understood that in other implementations, the userdetection unit 1042 and the content presenting unit 1044 may be locatedin separate computing devices.

The firstnode and the second node are both nodes, but they are not the same node.

The terminology used herein is for the purpose of describing particularimplementations only and is not intended to be limiting of the claims.As used in the description of the implementations and the appendedclaims, the singular forms “a,” “an,” and “the” are intended to includethe plural forms as well, unless the context clearly indicatesotherwise. It will also be understood that the term “and/or” as usedherein refers to and encompasses any and all possible combinations ofone or more of the associated listed items. It will be furtherunderstood that the terms “comprises” and/or “comprising,” when used inthis specification, specify the presence of stated features, integers,steps, operations, elements, and/or components, but do not preclude thepresence or addition of one or more other features, integers, steps,operations, elements, components, and/or groups thereof.

As used herein, the term “if” may be construed to mean “when” or “upon”or “in response to determining” or “in accordance with a determination”or “in response to detecting,” that a stated condition precedent istrue, depending on the context. Similarly, the phrase “if it isdetermined [that a stated condition precedent is true]” or “if [a statedcondition precedent is true]” or “when [a stated condition precedent istrue]” may be construed to mean “upon determining” or “in response todetermining” or “in accordance with a determination” or “upon detecting”or “in response to detecting” that the stated condition precedent istrue, depending on the context.

What is claimed is:
